IMPROVEMENT IN SMOKE-JACKS.

Specification forming part of Letters Patent No. 178,606, dated June 13,1876; application filed April 25, 1876.

To all whom it may concern:

Be it known that we, JOHN B. DEEDS and DAVID A. BRIDwaLL, of TerreHaute, county of Vigo, and Stateof Indiana, have invented a new anduseful Enprovement in Smoke-Jack for Locomotive Round-Houses, of whichthe following is a specification:

The accompanying drawing represents a vertical central section ofourimproved smokejack for locomotive round-houses.

The object of our invention is to provide locomotive round-houses withsmoke flues or jacks, by which a direct draft from the smokestacks ofthe locomotives to the outside of the roof of the round-house isproduced, and thereby the raising of steam facilitated at a saving offuel,.the drip of the flue collected and reconducted to the stack, andthe escape of smoke and sparks prevented, so as to secure the house fromdanger of fire by escaping sparks.

The invention consists of a-flue or jack with movable and balanced hoodand outside ventilators. The movable hood adjusts itself automaticallyby: surrounding conical rim, with drip-holes, to the top of thelocomotive smoke-stack.

Similar letters of reference indicate corresponding parts.

In the drawing, A represents a smoke flue orjack, of suitable sheetmetal, and of a size corresponding to the diameter of the smokestacks oflocomotives. The jack A extends through the roof of the round-house tosuitable height above the same, and is provided at the top part withventilating-tubes B and protecting top caps B, that prevent the windfrom blowing down the flue. Any approved ventilator construction thatsecures the required draft in the flue A may, however, be applied, as wedo not confine ourselves to the special arrangement shown. The lowerpart of the flue or 'leeting on the flue to the stack. of thesmoke'fiues in locomotive round-houses jack A is arranged at such heightabove the floor or track of the round-houses that the smoke-stacks mayreadily pass below the same. The lower part is made of somewhat largerdiameter than the upper part, for the purpose of guiding the movablesection or hood (3, that is equal in diameter with the upper part of theflue. ed by a central rod, and from a fulcrumed top rod, 1), that passesto the outside of flue, and has a weight, d, hung thereto, which nearlycounterbalances the hood, so that the same moves readily up and down inthe lower enlarged section of the flue. To the lower edge of hood (J isapplied an extension rim or flange, D, of inverted conical shape, alongwhich the top of the locomotive smoke-stack passes, so as to graduallyraise the hood until tbe stack is vertically below the flue. Drip-holese at the lower edge or joint of the hood and conical flange conduct thedrip col- The utility is obvious, as they, keep the same free of smokeand sparks, and admit the readier getting up of steam without any dangerof fire to the building.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent- 1. The combination, with jack-flue A, of ahood, 0, movable up and down therein, and provided with a flange, D,substantially as and for the purpose described.

2. A hood for jack-fines, provided with the holes eat the junction ofbody with the flange D, as and for the purpose specified.
